4. A throw-out bearing for shaft couplings comprising a cup-shaped collar formed of a single piece of sheet metal, and having a rim provided with pivots arranged at diametrically opposite points, and a member transmitting throw-out pressure, removably held in said collar, said rim having sufficient inherent resiliency to be selfflexed into resilient engagement with the periphery of said member.

5. A throw-out bearing for shaft couplings comprising a cup-shaped collar, having a rim provided with radially outwardly extending extensions at diametrically opposite points, presenting semicylindrical surfaces on their outer sides, said collar and extensions being formed of a single piece of sheet metal, and a member transmitting throw-out pressure removably held in said collar, said rim having sufficient inherent resiliency to be self-flexed into resilient engagement with the periphery of said member.
